Hi

I shoot RAW. When I open the file in PS it is 300 dpi.

I need to convert to PNG 300 dpi.

When I use the "export as"  I get PNG automatically 72 dpi.

Also when I use the "fast export as" it becomes 72 dpi.

How to get a PNG in 300 dpi?

Thanks Carsten

File > Save As > PNG  It should preserve the 300 ppi metadata.Also the Legacy File > Export > Save for Web will do the same if you set the Metadata to "All".The Quick Export functions does not preserve the original ppi metadata and so the image defaults to 72.

Thanks for that.

 

It is utterly stupid that this option is missing from export (not only quick export, but also not found in export as or save for web)

It's missing because Export is strictly for screen/web/mobile devices - where ppi is utterly irrelevant.

 

Pixels per inch only applies to printing, but if you're printing you don't use Export, you use "Save As", and you probably won't use PNG either.

 

So all in all, ppi has no place in Export.

Export is a foolish name for what should be Export For Web.

Yes, you're right, it is misleading. In most other software, export is what you do when you want to save out a final end product. So people might be forgiven for making this mistake if they're not familiar with Photoshop. Easy for us to forget.

File>Save As doesn't give the PNG option as it's blurred out. So what should one do?

Your image settings are not suitable. It needs to be 8 bit RGB. Don't forget to save the PSD FIRST before you make a conversion.

I tried in 8 bit RGB but after exporting, it still switches to 72ppi instead of 300ppi.

As we said, don't export. You must use Save As.

As I mention before, Save As doesn't allow PNG unless I do Export As

We've told you EXPORT WON'T WORK FOR YOU so please stop trying to use it. Yes, I know you report a problem with SAVE AS, but you have to solve that, and using EXPORT is not a solution. Please show a screenshot of your IMAGE > MODE menu.

Just for the record, and because it might help you understand this better: it's not actually 72 ppi - it doesn't have a ppi, not 72, not 300. The 72 number appears when you reopen the file into Photoshop, which for other reasons needs a ppi number. So 72 is just the default, but any number will do. Other applications may assign 96 or any other number.

 

The reason there's no ppi number is that it's not needed for what you use Export for: screen, web and mobile devices.

 

On screen, the ppi number is irrelevant and there's no need to worry about it at all. Ppi is for print only (and some secondary, derived parameters like font sizes and relative smart object sizes).

My image had to conform to print requirements for DTG which is Hi_Res png file recommended 150ppi and above. I don't know how to do it if it keeps reverting to 72ppi when converted from Phtoshop to PNG. That's why I was desperate for some advice as I can't seem to find a solution. Hopefully, someone can help me.

The official PNG specification states that the PNG resolution unit is in metres (not inches). This can be verified using metadata tools such as ExifTool.

 

So, a 300 ppi save as PNG from Photoshop would embed a value of 11811 ppm (pixels per metre). When Photoshop opens a PNG with this resolution metadata, it performs an “on the fly translation” from PPM to PPI:

 

118.11 x 2.54 = 299.9994 ppi... rounded up this is 300 ppi.

Using ExifTool:

 

Mac:

 

exiftool -overwrite_original -PNG-pHYs:PixelsPerUnitX=11811 -PNG-pHYs:PixelsPerUnitY=11811 -PixelUnits=meters 'Path to folder or file'

 

Win:

 

exiftool -overwrite_original -PNG-pHYs:PixelsPerUnitX=11811 -PNG-pHYs:PixelsPerUnitY=11811 -PixelUnits=meters "Path to folder or file"

unfortunately Save As a PNG flattens the image and names the layer Background, which is not what my client wants delivered. I used to be able to do this, and now I can't using the exact same actions. VERY frustrating.

PNG files will ALWAYS be flattened. Check out older ones you sent to your client to see this for yourself. This isn't a whim of Photoshop, it's the rules of PNG.

Yes, it is possible to save a PNG at 300 ppi with a transparent background, using SAVE AS. Do you face any difficulty with this when using SAVE AS on a document which already has the transparency set up? Or is your problem how to set up the transparency? Or is it that you can't get 300 ppi with SAVE AS? Or is it that you really, really want to use EXPORT instead? Or something else?

Thank you so much for your quick answer!!!

Yes I used SAVE AS and it save the PNG file with 300 dpi perfectly but no with transparent background.

And there is no option in the SAVE AS option to click transparent background.

I show you two screen shoots

Maybe is that I need to put the transparency set up and I don´t know why. Can you tell me? The file has not transparent background. I want to transform the normal file (with background) to a file with transparent background when I save it

I don`t want to use export because the file resolution is 72 dpi

Using File > Save as... can retain transparency and resolution metadata. A value of 11811 ppcm will be saved from a 300 ppi source file. This value will be shown in Photoshop as 300 ppi, even though the saved resolution value is not in pixels per inch.

 

Using File > Export as... can retain canvas transparency, however, resolution metadata will be removed. This defaults to 72 ppi in Photoshop

 

Using Export as... or Quick export from the layers panel will remove canvas transparency cropping down to pixel content and also remove resolution metadata.
